General

In the heyday of analogue synthesizers, Tom Oberheim and Dave Smith were both influential, cordially competitive designers. When legends like that work together, you just know the results will be astonishing! The result of their collaboration, the Sequential OB-6 polyphonic analogue synthesizer, is a great piece of technology with a delightfully retro look. Don't let its old-school controls and striking blue stripes fool you, though, the OB-6 is a brand new instrument with modern options such as MIDI, USB-MIDI, LEDs and room for hundreds of presets.

The Sequential OB-6 Analogue Synthesizer

The Sequential OB-6 is a six-voice polyphonic analogue synthesizer with two discrete voltage- controlled oscillators, a sub oscillator and a noise oscillator per voice. Their combined signal is sent to a 12dB filter (with low-pass, band-pass, high-pass and notch functionality), so you can colour the spectrum. An analogue VCA follows, and a comprehensive, studio-grade effects section completes the picture. Along the way, you'll have plenty of possibilities to shape your sound by means of envelopes, LFO, various routing options and real-time controlling. In other words, you'll certainly get the chance to express yourself!

Quality

With the OB-6, Sequential truly caters to sound designers. Thanks to a control panel full of knobs and buttons, editing sounds is a piece of cake. As such, your output will be nothing short of spectacular, while the classic housing with wooden side panels makes this analogue synth a real eye-catcher too. Are you on the lookout for a synthesizer that can really make a difference in your studio or on stage? You've found it!
